Legit grants for single mothers?

I'm trying to find a grant other than the Pell Grant. I'm wanting to start attending the LVN program at Kaplan College in Corpus Christi, TX in a few months, but I'm having trouble figuring out how to pay for it. Does anyone know of a legit grant? Everything I'm finding online so far seem like scams. PLEASE, only sincerely helpful answers! Thank you in advance!
